CSX Corporation (CSX) delivered a record second quarter, with revenue up 10% to $3.5 billion, operating income up 17%, and earnings per share up 23%, as the railroad rode a wave of stronger demand and executed on its cost-reduction program. The company raised its full-year outlook, now expecting revenue growth in the mid-to-high single digits, operating margin expansion of more than 350 basis points, and free cash flow growth of greater than 80%. The standout performer was domestic intermodal, whose volume rose 9% and revenue 26%, as customers increasingly turned to rail amid tightening truck capacity.
Record Growth, Tightening Truck Market
The quarter’s strength was broad-based, with volume up 6% across the network. “Total revenue increased 10%, benefiting from higher fuel surcharge combined with both volume growth and higher pricing across our merchandise, intermodal and coal markets.” — Kevin Boone · 2026-07-22 Even with a 160-basis-point fuel headwind, operating income grew 17% and margins expanded 240 basis points, reflecting disciplined cost control. Management cited efficiency gains across PS&O, third-party services, and corporate functions, while also absorbing higher incentive compensation and inflation.
The commercial team sees a structural shift in the trucking market. “We did see truck capacity tighten. I'd say, in particularly over the course of the last couple months with regulatory enforcement, I'd say on the Intermodal side, we're near the tail end of the domestic intermodal bid season for 2026...” — Maryclare Kenney · 2026-07-22 This has accelerated conversions, and management expects the trend to persist. Indeed, they noted that “in the last couple of weeks, it's adding about 2 – a couple of points, I would say, in terms of domestic intermodal growth.” — Maryclare Kenney · 2026-07-22
Customers are increasingly turning to rail for their supply chain needs and we are focused on earning their business through competitive service offerings and reliable execution.
The Truck-to-Rail Inflection Point
The truck capacity crunch is not a one-off. With regulatory enforcement removing capacity and higher fuel prices lifting rail’s value proposition, CSX is positioning itself to capture more of the $700 billion highway freight market. The completion of the Howard Street Tunnel has unlocked double-stack capacity and faster transit times, enabling the railroad to offer competitive service on new lanes. Maryclare Kenney, Chief Commercial Officer, drew a direct line to the structural opportunity: “There's a good amount of traffic that moves over the highway that is suitable for intermodal conversion.”
Management is also seeing the benefit in merchandise markets like forest products, where conversions have improved after a weak first quarter. The company’s prior commentary flagged the timing of pricing gains: “We have mentioned before that of our total book, it is only about 50% that we can touch in any given year, so we cannot touch everything at the same time, and there is a lag effect.” — Mary Claire Kenny, Executive (likely EVP, Sales and Marketing or similar) · 2026-04-22 That lag is now shortening as the truck market tightens. CEO Steve Angel has long championed the highway-to-rail conversion. In a prior call, he noted: “I think there are some opportunities you could certainly say that maybe some of these opportunities are coming forward as a result of what might take place from a merger standpoint. But I think the opportunity set has always been there. For railroads to work more closely together to take trucks off the road.” — Steve Angel, President and Chief Executive Officer · 2025-10-16
Cost Discipline and Service Investment
CSX’s cost-control program remains a key driver of margin expansion. Non-fuel expenses fell 2% year-over-year, with savings across every operating department. The company is investing modestly in headcount to support service reliability, a deliberate trade-off as volumes grow. “We've taken that into account as we think about balance of the year and in certain areas of our Merchandise portfolio.” — Maryclare Kenney · 2026-07-22 The railroad is also benefiting from data centers driving power demand, which supports domestic coal volumes and infrastructure-related freight.
The improved profitability is underpinned by strong operating leverage. Operating margin reached 36.0% in the latest reported quarter, up 560 basis points year-over-year. Management’s raised guidance for more than 350 basis points of full-year margin expansion indicates confidence in the momentum.
